ATTORNEY 6 J W I States, residin UNETED srerss rarssrorrlca BOSE Fe er; AND ANTONIO rnvomu-or BROOKLY NEW YORK,

To all whom it may concern:

Be it known that we, Ross FnvoLA and AN'roNlo FEVOLA, citizens of "the United of Kingsand tate of New York, have invented new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to improvements in radiators and particularly to steamer hot water radiators provided with individual heating devices, and the principal object is to provide a device of this nature which shall be simple of construction, in-

expensive to manufacture, and efficient for the purpose for which it is designed. I

Another object is toprovide novel oi r-,

culating devices.

Another object is to provide a novel safety control for the device whereby the flow of fuel will be automatically governed by the heat maintained in the radiator.

With these and incidental objects in view, the invention consists in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter described and claimed, and which are fully illustrated in the accompanying drawing comprising one sheet, in which:-

Figure 1 is a vertical sectional, end-toend view of our improved radiator.

Fig. 2 is a vertical sectional view taken substantially in line 2-2 of Fig. 1. V

Fig. 3 is an enlarged vertical sectional view of the burner and adjacent parts.

Fig. 4 is an enlarged detail view of the coil and burner cover, showing the door for permitting cleaning and lighting.

Like characters of reference refer to like parts in all views.

Referring to the drawing in detail, 1 represents the sections or loops of the radiator which are secured together and which are formed so as to provide top and bottom water-circulating passage ways 2 and 3 and connecting columns 4. Supported in any desiredmanner in the base of the radiator as upon a base plate 5 is a cylinder 6 of perforated or foraminated material which cylinder incloses the water heating coil 7 said coil being connected at one end to a pipe 8 which conducts water from the passageway 3 to the coil, and at the other end to a pipe 9 which conducts the heated water from the coil to the radiator sections.

.A gas burner 10 is also supported from plate 5 and extends into the coil. Burner 10 is connected to the gas or fuelpipe 11 t which is provided with a stop or regulatmore fully described hereinafter.

A door 14 is provided in cylinder 6 to give access to the coil and burnergfor cleaning thesame.

The pipe 9 is provided with outlets into passage ways 3'and 2 at 15-and 16 respectively, and at its upper end with a valve 17 and a funnel-shaped top element 18. V

- A steam drum or expansion tank 19 is secured to the top of the radiator and connects with passage 2 by two tubesf20 and 21. This tank is provided with a relief valve'22 and a steam gage 23, andalso with. an automatic gas control which will be presently described A water gage is secured tothe radiator and expansion tank at 24.

The automatic gas control comprises a member 25 provided at its upper end with a rubber or other flexible diaphragm 26 carrying at its center a pin 27 that supports one end of a lever 28 pivoted at 29 on a fulcrum secured to member 25. A weight 30 is adjustable on the other arm of lever 28, and a stop 31 is secured to the drum 19 and limits the downward movement of the weighted arm. The longer arm of-lever 28 is connected at its end by means of a chain 32 with the controllin lever 33 of the gas valve 13, said lever being normally held in its lowered open position by a spring 34 the lower end of which is connected to a bracket 35 secured to the gas pipe 11.

Where it is desired to have a direct connection to the water supply, the pipes may be connected in any suitable manner at 36.

In operation, the radiator may be filled at 18. The gas valve 12 is then opened and the burner is lighted. As the water is heated, it flows from the coil into pipe 9 from which it is discharged at 15 and 16 into the radiator, circulating as indicated by the ar-.

and thereby canse chain 3'2 to lift leve 33 to diminish the flow of gas, but stop 31 prevents the entire closingof thegas valve 13:

The eight 30 may heacljusted alongthe lever 28 so as to regulate the amount of pres sure necessary to cause closing of the valve.

Shouldanything go wrong so that the gas" would not be turned down, thearelief valve provided at The radiatonis aclaptecl to A While We have .des
